OWINGS MILLS, Md. — Returning to the practice field to continue preparations for Super Bowl XLVII, the Ravens were only missing one player from Thursday’s workout as linebacker Dannell Ellerbe did not participate.

The fourth-year defensive player has dealt with an ankle injury since late November and has received periodic days off after missing three games to begin the month of December.

Four players were listed as limited participants, including defensive tackle Haloti Ngata and tight end Dennis Pitta.

Meanwhile, the San Francisco 49ers released an injury report with no changes from Wednesday’s as linebacker Ahmad Brooks and tight end Garrett Celek were the only non-participants for Jim Harbaugh’s squad.

The Ravens will practice on Thursday and Friday before departing for New Orleans on Monday afternoon.
